The Redding 6.5 Grendel Deluxe Die Set (MPN: 84478) is a 3-die reloading system designed specifically for 6.5 Grendel cartridges using 0.264" (6.5 mm) diameter bullets. Precision-machined from heat-treated alloy steel on Hardinge super-precision lathes, these dies are hand-polished and ultrasonically cleaned. The set provides both full-length and neck-only sizing capabilities alongside bullet seating, giving reloaders the flexibility to process brass for maximum case longevity in bolt-action rifles or reliable feeding in semi-automatic platforms. Built with standard 7/8"-14 TPI threads, the dies fit standard reloading presses.

• Complete 3-Die Configuration: Includes a Full-Length (FL) Sizing Die with decapping rod and expander button, a Neck (NK) Sizing Die, and a Bullet Seating Die (ST).
• Dual Sizing Flexibility: The full-length die resets the entire case body and shoulder dimensions, while the neck die sizes only the neck to preserve fire-formed brass dimensions.
• Seating & Crimping: The seating die features an integrated precision bullet guide and a built-in roll crimp ring that can be adjusted for crimped or non-crimped bullet seating.
• Included Accessories: Ships in a dedicated storage box that doubles as a cartridge loading block, complete with a spare decapping pin and a hex adjustment wrench.

Who is the Redding 6.5 Grendel Deluxe Die Set for?

• Precision handloaders of 6.5 Grendel bolt-action rifle ammunition — the dedicated Neck Sizing Die in this 6.5 Grendel reloading die set resizes only the case neck for 0.264" (6.5 mm) bullets, preserving fire-formed case dimensions to maximise concentricity and brass lifespan.
• Reloaders assembling 6.5 Grendel ammunition for semi-automatic or multi-rifle use — the included Full-Length Sizing Die restores full body clearance and resets shoulder headspace across 7/8"-14 TPI reloading presses to ensure reliable chambering in AR-15 platforms or varied firearm chambers.

Less suitable for: Reloaders working with other 6.5 mm cartridges (such as 6.5 Creedmoor or 6.5 PRC) where a calibre-specific die set matching that exact chamber dimension is required, or reloaders using fire-formed brass across multiple firearms where a standalone full-length die set is needed instead of neck-sizing.
